[0037] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0038] See also Figures 2 to 9 As shown, the utility model provides an easy-to-assemble massage movement, including an outer frame 1, an inner frame 2 rotatably coupled to the outer frame 1, and a massage device 3 assembled to the inner frame 2, wherein the massage device 3 includes a massage arm 31 and a massage drive mechanism 32 for driving the massage arm 31.

[0039] In order to solve the problem that the frame used in the prior art, such as patent numbers CN114587976A and CN215779750U, consists of three parts, namely the middle frame and the left and right side panels, refer to Figure 1As shown, the middle frame has a bent portion in the up-down direction, which is not only difficult to form, but also affects the assembly operation of the massage device 3 in the up-down direction. In this embodiment, the inner frame 2 includes an inner bottom plate 21 and a pair of inner side plates 22 arranged at intervals in the left-right direction. The inner bottom plate 21 is configured to be open in the up-down direction perpendicular to the left-right direction to avoid hindering the assembly operation of the massage device 3 in the up-down direction. The inner bottom plate 21 in this embodiment adopts the above structure, which not only simplifies the structure of the middle frame and reduces the difficulty of processing, but also facilitates the assembly of the massage device 3 on the inner frame 2.

[0040] The massage device 3 includes a plurality of shafts extending in the left-right direction and parallel to each other, and the two ends of the plurality of shafts are respectively assembled to the pair of inner side plates 22, and the pair of inner side plates 22 can form an operating space for assembling the massage device 3 in both the up-down direction and the front-back direction. During assembly, the operator can first assemble the massage device 3 together, and then install the pair of inner side plates 22 on the massage device 3 in the left-right direction, and then assemble the assembled product to the bottom plate, which greatly simplifies the assembly efficiency of the massage movement; Figure 7-8 As shown, one side of the inner plate 22 has a bent portion, and a mounting hole is provided on the bent portion so that bolts can pass through to connect the inner bottom plate 21 to the corresponding inner plate 22, thereby completing the assembly operation of the inner frame 2 and the massage device 3.

[0041] It should be noted that in this embodiment, the left-right direction is the width direction of the massage core, the up-down direction is the height direction of the massage core, and the front side refers to the direction toward the user. Figure 3 direction shown.

[0042] Furthermore, in order to improve the stability of the inner frame 2, the inner frame 2 also includes a reinforcing member extending in the left-right direction, which is arranged at the first end 6 and / or the second end 7 of the pair of inner side plates 22 in the up-down direction, and is used to ensure the strength of the inner frame 2. The reinforcing member 23 is constituted as a plate body or a rod body, which has a simple structure and is easy to process. Figure 2-4As shown in FIGS. 7-8, in this embodiment, a reinforcing plate 23 is connected between the first ends 6 of the pair of inner side panels 22 in the up-down direction, and the reinforcing plate 23 is fixed to the pair of side panels after at least part of the components of the massage device 3 are assembled between the pair of side panels. Preferably, the reinforcing plate 23 is combined with the upper part of the pair of inner side panels 22, and is not mechanically connected with the inner bottom plate 21, and the inner bottom plate 21 is configured such that after the reinforcing plate 23 is removed, no blocking portion is formed at the first end 6 that can hinder the assembly operation of the massage device 3. In some embodiments, a reinforcing rod 24 is connected between the second ends 7 of the pair of inner side panels 22 in the up-down direction, and the reinforcing rod 24 is combined with the upper part of the pair of inner side panels 22, and the inner bottom plate 21 is configured such that after the reinforcing rod 24 is removed, no blocking portion is formed at the second end 7 that can hinder the assembly operation of the massage device 3.

[0043] The above structure can enhance the stability of the inner frame 2, and the reinforcing plate 23 and the reinforcing rod 24 can be assembled after the massage device 3 and the pair of inner side plates 22 are at least partially installed, and then assembled together on the inner bottom plate 21, which is simple and convenient to install. In this embodiment, the pair of inner side plates 22 and the upper and lower reinforcing members are assembled with the massage device 3 first, and then assembled together on the inner bottom plate 21, which greatly improves the assembly efficiency.

[0044] In this embodiment, the massage drive mechanism 32 includes a kneading component 321 and a knocking component 322, the kneading component 321 includes a kneading drive motor 321a, a kneading shaft 321b and an eccentric piece 321c for sleeve-fitting the massage arm 31 on the kneading shaft 321b, the kneading drive motor 321a is transmission-connected to the kneading shaft 321b via a first worm gear set 321d, the knocking component 322 includes a knocking drive motor 322a, a knocking shaft 322b and a connecting rod 322c for connecting the massage arm 31 and the knocking shaft 322b, the drive motor is transmission-connected to the knocking shaft 322b via a pulley 322d, the knocking shaft 322b is an eccentric shaft structure, so as to drive the massage arm 31 to swing via the connecting rod 322c, so that the massage arm 31 can perform knocking massage on the user.

[0045] The massage device 3 further includes a walking mechanism 33, which includes a walking drive motor 331, a first walking shaft 332, and a second walking shaft 333. The first walking shaft 332 penetrates the inner frame 2 and the outer frame 1 along the left-right direction, and the second walking shaft 333 penetrates the outer frame 1 along the left-right direction and is arranged on the other side of the outer frame 1 relative to the first walking shaft 332. The walking drive motor 331 is connected to the first walking shaft 332 through a second worm gear set 334. The massage device 3 can refer to the massage structure in patent number CN213911268U.

[0046] See also Figure 2-6 As shown, the walking drive motor 331 and the kneading drive motor 321a are respectively assembled on both sides of the massage arm 31, and are staggered to leave a position for the installation of the knocking drive motor 322a. The knocking drive motor 322a is arranged below the kneading drive motor 321a, and the pulley 322d is located in the middle part of the knocking shaft 322b, thereby reducing the width direction of the massage device 3 along the left and right directions. The above structure makes the structure of the entire massage device 3 more compact, and further reduces the width size of the massage movement. In this solution, by optimizing the structure, the massage movement can adapt to massage platforms of different widths; when it is necessary to adapt to a wide-sized massage platform, it is only necessary to increase the length of the walking shaft; when it is necessary to adapt to a narrow-sized massage platform, it is only necessary to reduce the length of the walking shaft accordingly, and it has a wider applicability.

[0047] In the technical solution, the inner frame 2 can rotate relative to the outer frame 1 so as to adjust the distance between the massage device 3 and the massage part of the user, thereby adjusting the massage strength of the massage device 3 on the user. In order to improve the assembly efficiency of the massage movement, the frame body 11 is configured to be open in the up and down directions to avoid hindering the assembly operation of the inner frame 2 in the up and down directions. In this embodiment, the outer frame 1 includes a frame body 11 and an outer stopper 12 extending in the left and right directions, wherein the frame body 11 adopts an integrally formed structure design, and has an outer bottom plate 11 and a pair of outer side plates 12 arranged at intervals on the left and right sides of the outer bottom plate 11. During assembly, the inner frame 2 and the massage device 3 are first assembled to the frame body 11, and then the outer stopper 12 is connected to the pair of outer side plates 12 by bolts, thereby completing the assembly of the outer frame 1, and the assembly is more convenient. In this embodiment, since the outer frame 1 is simpler in shape than the inner frame 2, the frame body 11 adopting the above structure can be integrally formed, which is simpler to process, and can also reduce the use of materials in the up and down directions, thereby reducing the production cost.

[0048] See also Fig. 9As shown, the pair of outer plates 12 are also provided with an axial hole for installing the first walking shaft 332, and the axial hole has a top opening on the side facing the massage arm 31, so that when assembling the inner frame 2 and the massage device 3, the first walking shaft 332 can be directly placed in the axial hole, which is convenient for assembly; the pair of outer plates 12 are provided with a through hole for the second walking shaft 333 to pass through, and the second walking shaft 333 is fixed to the pair of outer plates 12 by bolts, and can also be used as a connecting support for connecting the ends of a pair of outer plates 12, thereby ensuring the strength of the outer frame 1.

[0049] An airbag driving mechanism 4 is also arranged between the inner frame 2 and the outer frame 1 for driving the inner frame 2 to rotate. The airbag driving mechanism 4 includes an airbag 41 and an elastic member 42. The airbag 41 is provided with an air valve, which extends out of the outer frame 1 so as to connect to an external air source, such as an air pump, etc., so that the inner frame 2 can rotate relative to the outer frame 1 around the first walking axis 332 by inflating the airbag 41, thereby adjusting the massage strength of the massage device 3 on the user; the elastic member 42 is arranged at the end of the inner frame 2 that rotates toward the user, so as to ensure a stable connection between the inner frame 2 and the upper frame; in the present embodiment, the elastic member 42 is configured as a spring, one end of which is connected to the outer frame 1, and the other end of which is connected to the inner frame 2. Through the elastic action of the elastic member 42, the tension of the connection between the upper end of the inner frame 2 and the outer frame 1 can be ensured, thereby preventing the inner frame 2 from shaking relative to the outer frame 1 when the airbag 41 is not in use. Furthermore, a torsion spring 43 is sleeved on the first travel shaft 332, one torsion arm of the torsion spring 43 is arranged on the outer frame 1, and the other torsion arm is arranged on the inner frame 2. When the inner frame 2 swings forward, the other torsion arm is driven to twist, and when the inner frame 2 swings backward, the other torsion arm is reset. When the airbag 41 is not in use, the torsion spring 43 prevents the massage device 3 from swinging; through the cooperation of the elastic member 42 and the torsion spring 43, the swing of the massage device 3 can be reduced.

[0050] See also Figure 4-5 As shown, a limiter 5 for limiting the rotation range of the inner frame 2 is further provided between the outer frame 1 and the inner frame 2. The limiter 5 is arranged on both sides of the inner frame 2 and can limit the rotation range when the inner frame 2 rotates forward. In this embodiment, the limiter 5 is made of a flexible material, such as a braided belt. The braided belt has the advantages of low manufacturing cost and strong toughness, and can effectively connect the inner frame 2 and the outer frame 1 to avoid looseness.

[0051] The utility model further provides a massager, comprising a guide rail frame and the aforementioned massage mechanism disposed on the guide rail frame. The massager is, for example, a massage chair.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
